Halls ICON 8 8x12 Greenhouse 3mm Toughened Glass - Mill HR01329

Enjoy the freedom of an 8x12 greenhouse that offers generous space, comfort, and room to grow year after year.

The Halls ICON 8 8x12 Greenhouse is designed for gardeners who want room to grow, organise, and work without compromise. Its extended 8x12 footprint provides exceptional internal space, making it easy to arrange staging, grow a broad selection of plants, and move freely while tending crops. The additional length offers greater layout flexibility, supporting both productive planting and comfortable day-to-day use.

With increased internal proportions, this greenhouse accommodates taller plants and makes excellent use of vertical growing space. Whether you are raising seedlings, cultivating vegetables, or overwintering plants, the ICON 8 creates a bright, open environment that supports consistent, healthy growth throughout the year.

Ideal for gardeners planning ahead, the 8x12 layout offers a practical long-term solution that adapts easily as growing ambitions expand, without feeling cramped or restrictive.

 

 

Strong, dependable construction for everyday gardening

Built for reliability and long-lasting performance, the Halls ICON 8 8x12 Greenhouse features a precision-engineered aluminium frame with a durable mill finish. Naturally corrosion-resistant and virtually maintenance-free, the mill aluminium frame delivers strength and longevity while maintaining a clean, understated appearance that suits any garden style.

The greenhouse is glazed with 3mm toughened glass, providing excellent light transmission to encourage healthy plant development. Toughened glass is significantly stronger than standard horticultural glass and breaks into small, blunt pieces for improved safety, making it ideal for family gardens and regular use. The use of long, continuous glass panels enhances both stability and the greenhouse’s modern aesthetic.

A smooth-sliding door with a low threshold ensures effortless access, even when carrying trays, tools, or wheelbarrows. Manual roof vents promote effective airflow and temperature regulation, helping to maintain optimal growing conditions during warmer months.

 

Frame colour options and glazing choices

The Halls ICON 8 8x12 Greenhouse is available with three premium aluminium frame finishes, allowing you to tailor the greenhouse to your outdoor space. The powder-coated green frame blends naturally into traditional gardens and planting areas, offering a classic, subtle look among surrounding greenery. The black powder-coated frame delivers a bold, contemporary appearance, creating a striking focal point in modern garden designs. The mill aluminium frame offers a clean, neutral finish that complements all garden styles while showcasing the greenhouse’s refined structure.

Glazing options are available to suit different needs and preferences. 3mm horticultural glass provides excellent clarity and light levels at a cost-effective price, supporting strong plant growth. 3mm toughened glass offers enhanced durability and safety, shattering safely if broken, making it the preferred choice for long-term use and high-traffic gardens. Both options deliver reliable performance and bright growing conditions throughout the seasons.

Frequently asked questions

Do I need a base for my greenhouse?

In most cases, yes, a base is strongly recommended. A purpose-made greenhouse base makes installation far easier, ensures the structure sits level, and provides long-term stability. This helps protect both the frame and the glazing over time.

If your greenhouse is being installed onto an existing solid surface such as a concrete pad, brick base, or wall-mounted foundation, you may not require a separate steel base. However, where no suitable foundation already exists, a proper base is the safest and most straightforward option.

Occasionally, bases may be included as part of a special offer. If that applies, the option can simply be selected at zero cost when ordering.

Do I need professional installation?

All greenhouses are supplied with full instructions and many customers do successfully install them themselves. However, installation does require time, careful preparation, and suitable weather conditions. Many customers choose professional installation for added convenience and peace of mind. If you do opt for installation for your Icon 6 greenhouse, it is essential that the area is fully prepared ahead of time. This means the ground must be level, clear of debris, and easily accessible for the installation team.
